CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N0. 479,881, dated August2, 1892. Application filed April 4, 1892. Serial No. 427,590. (Nomodel.)

To all whom it may concern.-

Be it known that I, OTIS HOOD, a citizen of the United States, and aresident of Onset,in the county of Plymouth and State of Massachusetts,have invented new and useful Improvements in Oar-Oouplings, of which thefollowing, taken in connection with the accompanying drawings, is aspecification.

This invention relates to improvements in car-couplings for the purposeof automatically coupling railway-cars together without danger or injuryto the operator, and it is carried out as follows, reference being hadto the accompanying drawings, wherein- Figure 1 represents a sideelevation of a pair of cars coupled together by my improved device. Fig.2 represents a top plan of the improved car-coupler shown as coupled toanother one of like construction. Fig. 3 represents a longitudinalsection of Fig. 2 Fig.4 represents a longitudinal section of theimproved car-couplers shown in the act of being coupled together, andFig. 5 represents a detail side View of the outer end of one of thepivoted shackle-frames.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

A A represent a pair of railway-cars, on which E B are the hunters ordraw bars, having flaring mouths or link-sockets B B, as is usual incar-coupling devices. To the top of each draw-bar is pivoted at b aswinging shackle-frame 0, having lateral slots 0, in which is looselyheld the cross-bar D,having secured toit adownwardly-projectingshacklepin D, as shown in the drawings.

On opposite sides of the cross-bar D are located in the slot 0 elasticpackings C" O for the purpose of allowing the shackle-frame O to yieldlongitudinally when the cars are coupled together, and thus relieve thesaid shackle-frame from undue strain.

E E are upwardly-projecting cams or inclines on the outer ends of thedraw-barsBB, which serve to elevate the shackle-frame on the oppositebunter as the cars approach each other, and for this purpose I providethe outer end of each shackle-frame with one or moreanti-friction-rollersffi which during the coupling operation come incontact with the wedge E E, causing said shackle-frame O and itsshackle-pin D to rise sufficiently upward to enable the pin D to passbetween the said wedges E E above the mouth B, and finally to beautomatically guided into a perforation b in the draw-bar and throughthe link G, which is connected in its opposite end to the oppositedraw-bar by means of a pin 1)", as shown in the drawings. Eachshackle-frame O has an anti-friction roller f journaled on it back ofthe shaokle-pin'D for the purpose of guiding the latter into theperforation b after said shackle-frame has been raised to its highestpoint, when said roller f will come in contact with and roll against therear face of the wedges E E. The cars can be unshackled without goingbetween them simply by pulling on a cord H, attached to theshackle-frame, as shown in the drawings.

' This improved car-coupler maybe coupled to any of the ordinarydraw-bars simply by swinging the shackle-frame C out of operativeposition and coupling the link by the usual link-pins.

It will be noticed that each draw-bar has a pivoted shackle-frameadapted to be actuated by wedges on the opposite drawbar, theshackle-frame on one draw-bar being arranged to one side of theshackle-frame on the opposite draw-bar, so as to provide for automaticcoupling of one car with either of the ends of another car.

Having thus fully described the nature, construction, and operation ofmy invention, I wish to secure by Letters Patent and claim- 1. Theherein-described automatic car-coupler, consisting of draw-bars havingflaring mouths and a link connected to one of the draw-bars, combinedwith ashackle-frame pivoted to one of the draw-bars and having ayielding shackle bar and pin mounted in slots in said shackle-frame, oneor more anti-friction rollers on the latter, and wedge-shapedprojections and a locking-perforation on the opposite draw-bar,substantially as and for the purpose set forth.

2. The herein-described automatic car-coupler, consisting of a pair offlaring-mouthed draw-bars, each one having a link adapted to beconnected to the opposite draw-bar, apivbar, substantially as and forthe purpose set oted shackleframe, a yielding shackle bar forth. and pinmounted in slots in said shackle In testimony whereof I have signed myframe, one or more anti-friction rollers on the name to thisspecification, in the presence of 5 latter, and wedges and alocking-perforation two subscribing witnesses, on this 1st day of I 5for automatically guiding the locking-pin on March, A.
